Allow ReactiveCaching to support nil value

When :calculate_reactive_caching returns a nil value
this caused ReactiveCaching to schedule a worker
every time the code using :with_reactive_cache was called.

This issue caused an increasing amount of Sidekiq jobs
being created continuously.

Implementing this fix behind feature flag
:reactive_caching_check_key_exists
